What Are Cookies and When to Delete Them

Cookies are small files websites store on your device to remember you — login sessions, shopping cart contents, preferences, and tracking data. Delete cookies when: you want to log out of all sites, fix a website that is misbehaving, clear tracking data for privacy, or free up a small amount of storage.

Deleting cookies logs you out of all websitesYou will need to sign back in to every site — email, banking, social media, shopping sites. Have your passwords ready or in a password manager before clearing cookies.

Delete Cookies for One Specific Site Only

Chrome: click the padlock icon in the address bar → Cookies → select the site → Delete. This removes cookies for just that site without logging you out of everything else — useful for fixing a specific broken site.

Third-party cookies are being phased outMajor browsers are removing third-party tracking cookies. First-party cookies (from the site you are visiting) will remain — these are what keep you logged in. Deleting cookies periodically is still a useful privacy practice.

Frequently Asked Questions

Cookies store website data about you (logins, preferences, tracking). Cache stores website files (images, CSS, scripts) to load pages faster. Clearing cookies logs you out of sites. Clearing cache makes pages load slightly slower initially as files re-download. They can be cleared separately or together.
There is no single right answer. For privacy, clearing cookies monthly is a reasonable practice. If everything is working fine and you are not concerned about tracking, there is no technical need to clear them regularly — cookies are not harmful in themselves.
